PMD - Moisture Meter Series

PMD 2450

Precision Microwave Transmission Device

The PMD 2450 utilizes microwave transmission by measuring attenuation and phase shift to analyze moisture content. Originally developed by the founder of InduTech and continuously improved, this is the 4th generation of this instrument, with noticeably increased accuracy up to 0,1% , especially when dealing with thin layers and measuring non-homogenous products.

PMD 2450

Precision Microwave Transmission Device

The PMD 2450 covers the experience gained over 4 generations of the instruments, based on the microwave transmission and the phase method, which was developed by the founder of the company. The original method was remarkably improved by Indutech. This gains large advantages compared to earlier generations of the instrument, in a noticeably increased accuracy, especially for thin layers, inhomogeneous products and concentration measurements.

New Development!

PMD 2500

Precision Microwave Transmission Device (patented)

Is leading in Microwave Transmission Moisture Measurements. PMD 2500 is able to measure low layers down to 10 mm and high layers up to 5000 mm (dependent on the material) with highest reliability and accuracy. With different sensors the PMD 2500 can be use for a wide range of applications on conveyor belts, at chutes, dryers, silos, pipes etc. for determining moisture, carbon in fly-ash, density, solid content, consistency, pulp, brix, salt content etc.. New sensors, especially for the extreme extended frequency range, enables more and more customized applications.

Big advantagesThe modular set-up allows to install the evaluation unit at an ergonomic place with a distance of up to 400 m away from the measuring point.

■ protection class IP66 for indoor and outdoor installations

■ extremely wide frequency range from 300 MHz to 6 GHz

■ the microwave frontends are specified for a temperature range from -20 to +70 °C

■ certified for ATEX zone 22, optionally for zone 21 on request

■ meets all necessary regulations for Europe, USA and Canada according to CE, ETSI, FCC and RSS

■ the high measurement accuracy is ideal for closed loop control purposes

■ extremely thick layers, for e.g. silo outlets with a width of up to 2 m

Continuous developmentnew sensors, especially for the extreme extended frequency range, enables more and more customized applications.

EU Research Project “DRAGON” (FP7) – 30 8389 in 2012

The new PMD 2500 Precision Microwave Moisturemeter was developed within this EU Research Project. The aim was, to achieve resource efficiency by real time online analyzing the excavated material directly on the TBM Tunnel Boring Machine for separating useable minerals as resource. We developed within this Research Project the new PMD 2500 to measure moisture at a bypass belt with a material layer of 20 mm only. The extremely high accuracy and long term stability of the PMD 2500 guaranties high reliable moisture readings.
